Triumph Scrambler Custom

This Triumph Scrambler custom is a little unusual in that it was actually built by the engineers at Triumph as a study into what the Scrambler could evolve into over the coming years. This build is far from being just a slap of paint and a new muffler, every element of the original Scrambler was reworked and many production line components didn’t end up on the finished bike.

Work began with the engine, the head of the stock 865cc Scrambler engine was fully ported and skimmed to increase the compression ratio from 9.2:1 to 11.4:1. Larger inlet and exhaust valves were then fitted with high lift cams (using Daytona 955 profiles) were fitted and the throttle bodies are modified units from the Daytona 675.

The main frame is an entirely custom made unit machined from aluminium alloy and the subframe is fabricated from titanium alloy, the weight savings from these two elements a few others added up to 50 kilograms by the end of the build – an astonishing feat of weight loss that resulted in the completed (wet) weight of the bike being just 180kgs, down from 230kgs stock.

Further contributing to that weight loss is the carbon fuel tank by along with a carbon hugger, seat under-tray and headlight bowl. If you’re familiar with Triumph’s other motorcycles you might recognise that swing arm, it’s repurposed from a 2008 Speed Triple, it’s been turned upside-down and heavily modified in-house by Triumph engineers for the direct acting monoshock and chain idler gear.

One of the stand-out features of this build has to be those springs, they’re both units that were made specifically for this Scrambler. The front wheel now has travel of 300mm, and the rear wheel can move 250mm – this is all fully adjustable with high and low speed damping.

Although it’s exceedingly unlikely that Triumph will mass produce this exact Scrambler en masse, it is potentially a glimpse into what’s in the pipeline for the future. This is an exciting time for the humble Scrambler and we’re anticipating that the significant interest in the genre is going to continue to increase as people diversify from cafe racers into other classically styled motorcycles.

The story of the Dambusters has become legendary, officially known as Operation Chastise, it was an attack on German dams using bombs that bounced across the water (like a stone skipping on a lake) until they hit the dam wall, detonated, and caused catastrophic damage. The dams were vital parts of the German war machine,…

The beautiful BMW cafe racer you see here is the work of Elemental Custom Cycles based in Neustadt, Germany just outside of Nuremberg. The core philosophy of the garage is “Life’s to short to ride boring motorcycles” – which sound like words to live by to me. This bike is the latest project from the German…

The Cluster Bomb Drinks Cabinet is one of the more famous creations from Plane Industries, a firm that makes high-end furniture from decommissioned aircraft parts and munitions. Each drinks cabinet is made from a decommissioned (and obviously defused) BL755 cluster bomb originally designed and built by Hunting Engineering Ltd. for the Royal Air Force. The…

To say that the Greeves Challenger, and all Greeves motorcycles, were ahead of their time is to significantly understate the remarkable foresight of Bert Greeves and his lightweight two-stroke off-road racing motorcycles. Bert developed the first examples of his scrambles and trials machines in 1952, almost 20 years before lightweight two-stroke motorcycles would rise to…
